The present invention relates to a luminous slab made of transparent or translucent material (glass, for example), lighted from the underneath, by using SMD LEDs, being used for plating floors, walls and ceiling for decorative or safety purposes. The luminous slab, according to this invention, comprises a transparent or translucent glass tile (1), which has fixed on one side a printed circuit board (3). The printed circuit board is fixed on the glass tile by using a distance separator (2) and an A+B adhesive. On the printed circuit board (3) on the face towards the glass tile there are mounted many SMD LEDs (4) laid in order to obtain the desired luminous effect Depending on the LEDs number and their disposal and on the colour of the glass tile (1), the LED lights (4), in various intensity and models, will be seen through the glass tile (1). The electric supply is made through two electric contacts (5) on the lower side of the printed circuit board (3) where two electric wires (8) are tin solder fixed, of which length depends on the distance towards the power supply. On the rear and side face of the assembly glass tile (1) - distance separator (2) - printed circuit board (3) is applied a continuous layer (9) of a known silicone type for tightness purpose. |
